Parent virtual had disk has been deleted

17th May 2009, 20:33

Hi

I have been trying to install a training pack for Microsoft BizTalk course 2934a. I have downloaded multiple VHDs and followed the instructions (I think!) for installation. However, on attempting to start one of the VHDs from the Virtual PC 2007 console I get the message "The parent virtual hard disk has been deleted or has been moved from its previous location. Please select the new location of the parent virtual hard disk". At this point it's telling me that it's looking for Base05D.vhd. I already have a activated copy of this huge base disk so I browse to the location and select it. The I get the message "The virtual hard disk's parent appears to have been modified without using the differencing virtual hard disk" (does anyone know what this means?). I click ok then the I get the shutdown dialog with the "What do you want to do with your virtual hard disks?" and an option of "Commit changes to the virtual hard disk" etc.

I have checked the vmc files in notepad and all the paths seem to be ok. I've also used the virtual disk editor to check the parent disk references, all looks to be in order. The VM I'm trying to start uses a base disk which uses another base disk which uses another base disk. All of the base disk are present in the expected location.

The base disks are not activated - activation is on the course disk (first differencing disk) and then applies to the modules (second differencing disks)
Just retrieve Base05D from the DVDs you received with your MCT welcome pack and try again
